D.1 Coax Cable Preparation
NOTE: The procedures in this section, for preparing coaxial cables, are meant to
be generic. Cables and connectors should be installed per manufacturer’s
requirements specific to the brands preferred. In general, specific and detailed
instructions are for RG-6 cables and connectors, only.
Use high quality coaxial outdoor cable to connect the Evolution X7 Satellite Router to the
Outdoor Unit (ODU) equipment. iDirect recommends that a solid copper center conductor,
coaxial cable be used with a minimum of 60% + 40% braid and double foil shield to connect the
equipment, such as:
•
RG-6 — 0.04 inch (1 mm), outdoor rated, Quad Shielded, solid bare copper center
conductor, for cable lengths less than or equal to 225 feet (68.5 meters)
• RG-11 — 0.064 inch (1.6 mm), outdoor rated, Quad Shielded, solid bare copper center
conductor, for cable lengths less than or equal to 400 feet (121.9 meters)
Before connecting the cables, connectors on each end must be installed.
The center conductor must be straight and extend 1/8 inch (3.2 mm) beyond the end of the F-
connector, and the connector should be securely crimped to the cable.
NOTE: iDirect does not recommend using RG-59 with solid bare copper center
conductor. RG-6 or RG-11 Quad Shield or other outdoor quality, 75-ohm type of
coax can be used.
If different types of coaxial cable are used other than the recommended quad shield RG-6,
the following problems can occur:
•
Co-channel Interference – If signals at the same frequency are carried on long, parallel
runs of coaxial cable (for example, in cable trays, or riser) interference can occur
between the signals
• Higher quality cable helps to prevent this with better shielding
